.To all 'Loh/mt 1'15 mfr/.7j concern,.-

Be itkuown that I, HARRY H. HELMICK, of the city of Minneapolis, countyof Hennepin, State of Minnesota, have invented certain new and usefulImprovements in Computing-Machines, of which the following is aspecification.

My invention relates to computingmachines, and in particular to thatclass of computing-machines in which the figures and to-` tals areprinted upon a slip or strip of papel'.

The object of my invention is to provide a computing-machine which shallbe of a simple and strong constru ction, which cannot readily get out oforder, and, further, to provide a device of this class which shall beneat and compact and occupy but a small space upon a desk.

A further and more particular object is to provide a computing-machinewhich shall opcrate in an extremely easy manner, few movements of thehands being required.

A further object is to provide a machine wherein the Strip of paper andthe numbers thereon are in plain sight and within easy reach, and,further, to provide a machine which will permit of a very rapidoperation and will produce accu rate and clear work even when the keysare manipulated at a high speed.

'To these ends my invention consists generally in a computing-machine ofthe construction and combination of parts all as hereinafter described,and particularly pointed out in the claims.

My invention will be more readily understood by reference to theaccompanying drawings, in which- I Figure 1 is a vertical longitudinalsection of a computing-machine embodying my invention. Fig. 2 is atransverse vertical section thereof on theline .fr a; of Fig. 1. Fig. 3is a partial plan View of the front end of the machine on the line d dof Fig. 2, showing the means for releasing the stops of thestopscarriage. Fig. 4 is adetail view showing the connection between thecommon depression-bar and the rocking shaft that controls the forwardmovement of the carriage.

Fig. 14 is a longitudinal section showing themeans for reversing the parts when it is desired to compute and printtotals. Fig. 15 is a reduced plan View of a complete machine. I

I inclose the workin g parts of in y machine in lu the forward end ofthis casing I provide the transversely movable stop-carriage 3,arranging the same in the upper part thereof. The carriage 3 has theform of an open-ended metal box, from the front side of which arms 4project to sliding bearings upon a smooth frame-rod 5, while the otherend of the carriage is supported by rollers G, movable on a stationarytrack 7. Small arms S are pivoted on the side of the carriageframe tocarry the toothed ratchet-bar 9.85

(See Fig. 2.) This ratchet-bar is adapted to be engaged by the doublepawl device 10, similar in operation and construction to the device forreleasing a type-writer carriage (see Figs. l and 2) on the rockingshaft l1. The shaft 1l is supported in the frame parts 12 and isarranged to be rocked hack and forth through the use of the lateral arm13, connected with the depression-bar 14. (See Figs. 2 and 4.) As shownin these figures, the depression-bar 14 has inwardly-extending arms l5,pivoted on the sanne shaft 1G whereon the key-levers 17 arejournaled.The spindles 1S of the ten keys 1 8 are adapted to move up and downthrough the guide-plate 20 and have their lower ends pivoted to ltheouter ends of their respective key-levers 17. These levers extendinwardly and their inner ends are of the same length, measured from theIOD shaft 1G, and each has abroad llatfoot or end 21, adapted to engageoppositely-positioned pins 22 in the carriage, (see Figs. 1 and 2,) andsprings 22 are provided to draw back the keys after the stops have beenlocked in their raised position. Irrespective of arbitrary conveniencecharacters l employ but ten keys, bearing or representing the ten (i0,?? E( 1,77 C2777 LG 3757 HLLU C( 5,77 i( U7?) 7, 8, and 9, the use ofduplicates being rendered unnecessary by the employment of the shiftingcarriage 3, which controls the action of the type -carrying bars 32. Thestop-carriage 3 may be provided with any number oflongitudinally-arranged rows or series, each of nine vertically-movablestoppins 22,the pins of each row being transversely opposite thekey-levers 1T and keys 0 to S, respectively. A ninestop for all typebarsis provided in a fixed rib 22' on the forward edge of the carriage. (SeeFig. 1.) The key-lever of the nine-key simply operates to release thecarriage and allow it to move laterally one step. rl`he stop-pins 22extend through the top and bottom plates of the carriage 3 and are eachprovided with a shoulder or collar near the lower end and are normallyheld down by light springs 2i. (See Figs. l and G.)

Alongside of each row of stop-pins I provide a longitudinally-movablelocking-bar 25, provided with a lateral pin 25 for each stoppin andadapted to snap back beneath the collar or shoulder on a pin when thepin is raised. The keys are operated one at a time, and the depressionof a key will raise the stoppin which happens to be over the inner endof its key-lever. At the same time that a key is depressed andimmediately after the raisi ing and locking of the stop-pin 22 thecarriage 3 is released by means of the rocking dog 10 and will travelone notch tothe right, bringing the next row of stop-pins over the innerends 21 of the key-levers 17. Successive operations of the keys 1S willtherefore set np a single pin 22 out of each row or series ofstop-pinsas many pins being raised as there are keys depressed-exceptwhen the key 9 is struck, when the carriage is simply moved to theright. Each movement of the carriage .5 therefore represents a figure,and all the movements together represent a given number, running fromthousands through hundreds, tens, units, and decimals or simply throughunits and decimals or through decimals only, according to the number ofkeys used. The numbers are then practically set up in their proper orderfrom left to right. NVhen the carriage is released, as described, it isdrawn along by means of a spring 27, act ing on the pivoted lever 26,connected to the carriage 3. At the end of al complete operation of themachine, the other portions of which will be hereinafter explained, thecarriage is thrown back to the left or normal position by a rockingmovement of the shaft 28, whereon the lever 26 is secured, theratchetteeth of the bar fl slipping back readily over the double dog 10.lVhen the carriage is thus thrown back, all of the stop-pins 22 arereleased by the engagement of the outer ends of the lockingbars 25 withthe stationary returning-bar 2li, fixed in the frame and having thebeveled end or corner 30, the locking-bars 25 being thus formed backagainst the tension of their individual springs 31. (See Figs. 1, 3, andG.)

The stop-pins 22 in the carriage are employed to limit the forwardthrust of the combination type and rack bars 32, of which there are asmany as there are longitudinal rows or series of stop-pins in thecarriage. Each type and rack bar 32 is provided on its ripper edge witha series of ten numeral-types while the lower edge of the bar hasgear-teeth Si, with which the adding-wheels 91 are adapted to mesh, aswill be more particularly explained hereinafter. The bars 32 are freelymovable in longitudinal guides, and for each bar a bell-crank lever 3Gis provided, the lever being pivoted on a transverse shaft 37 in thebottom of the casing, strong springs 38 being connected therewith. Freemovement of the bars and their levers is permitted by the employment ofthe slot-and-pin eonneetions shown in Fig. 1. Itis obvious that when thebell-cranks are released from the cross rod -lO the bars will be quicklymoved forward until their' forward ends 3f) engage the pins 22, set upin the stop-carriage The type-bars 32 are normally held back by across-rod 40, arranged between opposite arms t1, secured upon the mainshaft 42 ofthe machine. (See Figs. S and 13.) The operating-lever `rt3has its lower end secured upon the shaft i2, and when the lever isforced back the rod 40 will obviously be swung down out of the path ofthe bellcranks 3U, thereby permitting the rack-bars to move forward whenthus released, and when a fewer number of stop-pins are set up thanthere are rack-bars l provide a separate lock for the bars, said lockconsisting in the transversely-movable bar or slide if, attached to andmovable with the stop-carriage and so arranged that the first movementof the stop- Carriage will carry the slide eti beyond and out of the wayof the first type-bar, the second movement beyond the second type-bar,and so on, so that just as many type-bars will be freed as there arekeys operated. The type on the bars 32 and the stop-pins 22 on thecarriage 3 are so arranged that whatever pins are engaged by thetype-bars the type on the said bars will be in line beneath thetransverse slot 4:5 in the top of the casing. (See Figs. 1 and l5.)Thetype run0, 1, 2, 3, ttc., from the front end of each bar, while thekeys and the stops to be actuated thereby are so arranged that the O isnearest the forward end of the typebar, l next, then 2,77 ttc. Thereforein each row the stop representing the O key will be nearest the forwardend of the type-bar in the row of type-bars, so that in case two keysare struck lOO IIO

osmose E at the same time the stop for a smaller key will cut out thoserepresenting larger n um bers.

The swinging movement of the cross-rod 40, as shown in Figs. 1, 5, 12and13, may be employed to throw back the stop-carriage. As illustrated inFigs. 1, 2, 5, 7, and 12, the shaft 2S, on which the lever 26 issecured, is provided with a bevel gear-wheel 70. A short shaft 71 isarranged transversely to the shaft 2S and has a bevel-gear 72, meshingwith the gear thereon. On the otherend of the shaft 71 is an arm 73,connected by a pivotal link 74 with the lower end of a vertical lever75. (See Figs. 1 and 12.) The upper end of this lever extends into thepath of the moving` rod 40, so that as the rod is thrown back and up atthe end of the operation of the machine the lever 75 will be forced backto rotate the two shafts 28 and 71, operate the lever 26, and move backthe carriage 23. 'llo prevent the carriage being moved laterally by thedownward movement of the rod 40, I construct the lever 75 in two parts,the upper part being pivoted on the lower part and adapted to breakforward against the tension of a light spring 77. By this arrangementthe upper end of the lever 75 may be depressed without moving the lowerpart, which is connected with the shaft 28. Furthermore, when it isdesired to print the same num ber several times, in which case it isdesirable to allow the stopcarriage to remain stationary, the throw-backmechanism may be disengaged by simply throwing out the clutch 78, apullbutton 79, connected with the clutch by a short lever S0, beingprovided for the purpose. (See Figs. 12 and 13.)

4G represents a paper-feeding roll arranged at the rear edge of the slot45 and suitably supported in fram e-bearings. Thepaper strip 48 iscarried upon the independently -supported roll 49 and is carried betweenthe roll 4G and the idler-roll 50 and then out and across the slot. (SeeFig. 15.) An inked ribbon 48/ extends across the slot, and an advancemechanism is provided therefor. w

52 represents a shaft arranged in bearings 53 and carrying as manyhammers 52 as there are type-bars 32. (See Fig. 15.) These hammers 52'are loosely journaled on the shaft 52, and from the end of the shaft anarm 54 projects down through the casing into position to be engaged bythe pin or lugs 55, extending from the lever 43. This arm 54 is securedupon the shaft 52 and is acted upon by the spring 5U, tending to drawthe same back, and thus thrust forward the pawl 47, pivoted upon theupper end of the arm and operating on the ratchet 57, provided on theend of the paper-feeding roll 46. (See Figs. 1 and 1.3.) Backwardmovement of the roll is prevented by a spring-detent 5S. A rod 59extends between the forward part of the arm 54 and a like arm on theother end of the shaft 52 and is parallel with the shaft 52. The hammers52' have stop-shoulders (i0 and are normally held against this rod bylight springs 61, this arrangement being employed in order that thehammers may be independent from one another to strike upon type whichare not of exactly the same height. It is obvious that the hammers mustbe released quickly at the time when the operating-lever 43 is nearingthe end of its stroke or throw and must be held at other times, and forthis purpose I provide a spring-hook 63, conveniently journaled on theshaft 42 and adapted to engage an arm or lug 64, extending from the rearside of the arm 54. (See Figs. 1, 8, and 13.) The hook (53 is thrown outof engagement with the lug 64 when the pin or lug 55 on theoperating-lever 43 strikes the hooks 63. To raise the hammers 52slightly oif the type aftera stroke, I provide a small cushion-springG5, on which the arm 54 rebounds. (See Fig. 1.) A suitable spring 66 isarranged around the shaft 42 .for holding the hook 63 forward. (See Fig.13.) On the return of the operating-lever 43 to the position shown inFigs. 1 and 13 all of the hammers will be raised and locked in a raisedposition by the engagement of the pin 55 with the lower end of the arm54 to swing the same up, so that the lug G4 will catch beneath theshoulder on the hook G3.

By means of the mechanism thus far described a series of numbers of fromone to nine figures each maybe printed upon the strip of paper insuccession, the printing being done on the under side of the sheet.

So far the maehineis complete. Amachine of this class is not, however,thoroughly complete without means for adding a series of numbers andprinting the total thereof, and I therefore provide an adding mechanismto operate in connection with the rack-bars Within the casing andbeneath the printingslot 45 in the top thereof I provide the two frame-s tandards 83, each of which is provided with al slot S4 in its upperend. (See Figs. 7 and 15.) rThe middle parts of the standard areconnected by a stationary rod S5. On the opposite ends of the shaft orrod I provide similar levers St', provided with camgrooves S7 in theirupper ends, said grooves being adapted to receive the ends of the shaftSS or small rollers SB'thereon. (See Fig. 11.)

The shaft preferably has square parts 89,

adapted to slide in the slots 84 and to prevent rotation of the shaft8S. (See Fig. 1l.) The vertical movement of the shaftis brought about bythe swinging of the levers 86. The cam-levers 86 are moved forward andback by means of the links 90, (see Fig. 13,) connected with thelever-arms 4l on the shaft 42, and in order to allow sufficient time forthe type-bars to move forward before the cog or adding wheels 91, whichare arranged on the shaft SS, are raised vinto engagement therewithshort slots `92 are provided in the arms 41, with the link-pins 92'working therein to the ends of the slots, the slots being of less lengththan the full throw of the operating-lever. Thus d n ri ng the last partof the IIO movement of the lever the a `ldingwheels 91 are raised intomesh with their respective type-bars The adding-wheels 91 arejou rnaledand move independently on the shaft SS. As they are raised intoengagement with the type-bars .52 only after the latter have completedtheir forward movement, the addingwheels 91 are operated by the backwardmovement of the type-bars when the operatinglever 3 is drawn forward tocarry the rod 40 into engagement with the bell-cranks 36, connected withthe bars The adding-wheels 91 have ten teeth, just as the type-bars haveten type The carrying mechanism for moving the next wheel of a higherorder one tooth for each complete rotation of the preceding wheel of alower order is best shown in Figs. 1,7, 8, 10, and 11. As shown therein,a lug 93 extends from the left-hand side of each adding-wheel, the lugpreferably conforming to the shape of one of the teeth.

Two movable frame parts Slt are arranged upon opposite ends of theshafts S5 and S8, the upper ends of the frame parts 91 being securedupon the shaft SS,while the lower ends are vertically slidable on theshaft S5, owing to slots 95, provided in the said ends. Between themiddle and rear parts of the framepieces 9i a stationary or iixed shaftor rod 9G is secured to receive the locking pawls or detents 97,normallypressed up by springs 97. (See Fig. 1.) The pawls 97 are arranged uponthe shaft 96 and extend between the addingwheels 91 and are providedwith the upwardly extending and inclined lugs 98, (sce Fig. 1,) adaptedto be struck by the lugs 93 on the adding-wheel to the right thereof,thepawls 97 controlling the action of one wheel upon the sueceeding wheel.Each intermediate mechanism is completed by a vertical lever 100,pivoted upon the shaft S5, and a second vertical lever 101, providedwith a lateral lug 102 and pivoted upon a cross rod orshaft 108,whichrod is fastened to the lower forwaidly-projecting ends of the parts 91and moves therewith, as shown in Fig. S. Springs 104 and 105 areconnected with the lower ends of the levers 100 and 101 to draw the sameback and throw their upper ends forward whenever released. The upper endof eachlever100 has the form of a segment of a gear having two teeth anda notch between the same to mesh with the teeth of the overlyingadding-wheel 91 when the same is dropped into its lower position. (Shownin Figs. 1 and 10.) The lug 102 on the lever 101 is adapted to lie inthe notch 10G in the pawl 97, and the rear edge of the lever 101 isadapted to engage the forward edge of the lever 100, in which positionthe lug 102 will be seated in the notch 10b' and lool; both levers 100and 101. lVhen the pawl 97 is depressed through the engagement of thelug 93 on the preceding adding-wheel with the lug 9S upon the pawl, thelug 102 is disengaged from the shoulder on the pawl 97, whereupon thelever 101 will spring out of engagement with the lever 100, after whichthe l pawl is held down by the lug 102. stop 10ivv l l l is preferablyprovided at the end of the pawl 97 to limit the movement of the lever101. lVhen the lever 100 is thus released, its spring 10-t will throwout its upper end and thereby rotate the addin g-wheel one tooth. Thethrow of the lever 100 is controlled and timed by means of a swingingcross-bar 108 to engage all of the levers 100, and itself adapted to beoperated by the swingingcross-rod 40. lVhcn the latter is thrown down,the lever-arms 109 of the cross-bar 10S, pivotcd onlixed shaft or shafts110, will be released and be dra-wn up by the spring 111 to carry thecross-bar 10S up behind the levers 100, while when the swinging rod 10is restored the cross-bar 10S will be dropped or thrown down beneath theprojections on the back of the levers 100, thereby permitting the sameto be drawn back by its spring 10t to throw forward its upper end androtate the wheel, providing the lever 100 has been released fromengagement with the lever 101. For restoring the two levers 100 and 101a cross-rod 112 is provided between the lower ends of the cam-levers S6,whereby as the operating-lever 13 is thrown back to raise theadding-wheels 91, with the pawls 97 and levers 101, the bar 112 willstrike the lower ends of such of the levers 101 as have been previouslyreleased and move the same back against the levers 100 and thence intotheir normal position, in this way restoring the levers 100 and thepawls 97.

The tens are carried forward in the following manner: By moving thelever e3 toward the left the adding-wheels will be raised intoengagement with the teeth on the under side of the rack-bars after thebars have completed their forward movement. The shafts 9G, S8, and 103are moved vertically with the adding-wheels,while the shaft S5,carryingthe levers 100, remains stationary, so that when the adding-wheels areraised the teeth thereon will be disengaged from the segment-gear on theupper endof the levers 100. The addingwheels having been raised intoengagement with the teeth of the rack-bars upon moving the levert-5forward the rod 10 willbe brought into position to engage the uprightlevers 3G, and as the lever el-S is moved still farther forward saidlevers 3G will be returned to their normal position, at the same timedrawing the rack-bars back and rotating the addingwheels that are inengagement with the teeth thereof.

Suppose the units-wheel to be rotated so that it stands at 9. It isevident that the next movement of the wheel will bring the lug 93 intoengagement with the inclined surface of the lug 9S, thereby depressingthe pawl 97 and unlocking the lever 101. The lever 100 will be preventedfrom moving by the lever 109 until such time as the adding-wheels havebeen dropped, so that the teeth of the same are in engagement with theupper end of the levers 100 and the lever 109 has been disengaged fromthe lever 100 bythe return move- ICO ment of the rod 40, and in no casedoes the rod 40 act upon the lever 109 to release the levers 100 untilthe adding-wheels have been dropped to their normal position. W hen thelever 109 is moved to the position shown in Fig. 1, the levers 101having been previously unlocked, as described above, the springsprovided at the lower end of the levers 100 will operate the same andadvance the tens adding-wheel one tooth. Should the tens-wheel stand at9, the movement of the rack-bar will cause the lug 93 on the tens-wheelto depress the pawl 97 and unlock another lever 101 in the same manneras described with reference to the unit-s-Wheel, and the addingwheelshaving been dropped back to their normal position in engagement withthelevers 100 and the lever 109 being operated by the rod 40 the spring104 will operate another lever 100 and advance thehnndredtlis-wheel onetooth.

The totals are ascertained from the lfinal relative locations orpositions of the adding-k wheels 91, or, more particularly, of the sidelugs 93 thereon. These positions are ascer tained by rotating all of thewheels in the opposite direction from their ordinary movement and untiltheir lugs 93 strike the forward sides of the lugs 98 upon the pivotedpawls 97. As the pawls 97 rise with the wheels, these movements are madethrough the rack-bars 32, the wheels being first raised into engagementtherewith and the rack-bars then released. The springs 38 in connectionwith the rack-bars will cause each of the same to move forward as far asthe lug 93 upon its adding-wheel 91 will permit. The totals will then beshown upon the bars 32 by the type 33 beneath the slot 45 in the top ofthe casing 2 and may be printed therefrom.

inasmuch as the backward movement of the rack-bars 32 is commonlyemployed for rotating the adding-wheels 91 and computing the numbersfrom the relative position of stops 22'in the stop-carriage 3 and as theopposite movement is employed when it is desired to print the totals ofthe wheels it is necessary to accommodate the part-s of the machine tosuch backward or reverse movcment. Thisl accomplish by simply changingthe pivotal connections of the camlever links 90 from above the centersof the operatingarms to equal distances below the same, so that amovement of the main lever 43 will result in reverse movements of theother parts.

Slots 114 are provided in the opposite operating-arms 4l, communicatingbetween the slots 92 and the lower curved slots 115, into which the pinsupon theends ofthe ea|n-lever links 90 may be thrown by means ot' thepivoted adding-lever or bell-crank 11b, 'preferably arranged upon thatside of the machine opposite the operating-lever 43 and journaled on thestud 11(5, as show-n on Fig. 14. The

link 90 upon this side of the machine is provided with an extension 90,pivot-ally con* neeted to the lower end of the lever 110 by the link90". Thelever 11G operates against a strong spring 117, having one endsecured to the side of the machine, and its otherto the extension 90'.The opposite end of the link 90 is connected with the similar link 90upon the other side of the machine bya rod 91. (Shown in section in Fig.14.)

When it is desired to add the columns of dgn res printed from therespective type-bars, the lever 11G is thrown to the position indicatedby dotted lilies in Fig. 14, therebyraising the adding-wheels 91 intoengagement with the teeth 34 on the under side of the type-bars 32, andby operating the lever 43 each type-bar will be allowed to move forwardun til the adding-wheel with which it is in engagement is stopped by itslug 93 coming in contact with the lug 98 on the adjacent pawl 97. Aseach adding-wheel 91 had been rotated by the backward movement of thetype-bar 32 as many teeth as its type-bar had been moved forward inprinting the column, it is obvious that the number of teeth on eachadding-wheel 91 between the lug 93, and the lug 98 on the pawl 97 willcorrespond to the number of units in the column to beadded, and wheneach adding-wheel is stopped by its lug 93 coming in contact with thelug 98 the numeral shown on each type-bar 32 beneath the slot 45 willindicate the sum of the units printed from that particular bar plus thesum of the tens carried forward from the preceding bar. Further, as noneof the typebars 32 could move forward to perform the adding operationunless the locking-slide 44 upon the carriage was removed, l provide arocker arm or arms 118 on the rod 5, at the forward end of the machine,and arrange a cross-rod 119 between the ends of the rockerarms 118, saidrod being adapted to be raised by the engagement of the lever 11G withrthe inner end of the rocker-arm, and this movement being utilized toswing or raise the ratchet-bar 9 on the carriage out of engage ment withthe double pawl 10 beneath it, so that the carriage may move out, andcarry the locking-slide 44 away from the type-bars.

A simple arrangement for slowly moving the ink-ribbon 48 is shown inFig. 7, wherein 120 represents spools upon which the oppo site ends ofthe type-ribbon are turned, and 120' rolls over which the ribbon passesas the spools revolve. These spools 120 are arranged in connection withbevel-gears 120, adapted to be engaged by bevel-pinions 121, arrangedupon a verticallymovable sleeve 121, geared to the vertical shaft 122.The shaft 122 is permanently geared by bevel-gears 122 and 122" to theextended ends of the shaftpbelonging to the paperfeeding roll 46.

The direction of movement of the ribbon 48' may be altered by shiftingone or the other of the pinions on the sleeve into engagement with itsspool. For shifting the IOO IIO

sleeve I provide a pushnblock 123, operated by a knob 124, extendingthrough the side of the casing 2,

Briefly, the operation of the machine is as follows: The operatorstrikes the keys and the carriage moves along to its proper posi tion.By operating the lever i3 the rod l0 is moved out of the path ot thelevers 3G, and such rack-bars as are not held in their normal positionby the stops ett are permitted to move forward against their respectivestops that are set up by the operation of the keys. During the movementof the lever i3 the hammers are released and allowed to fall upon thepaper and print thereon from the numerals or characters provided uponthe rack-bars beneath. When the operating-lever is drawn toward thefront of the inachine, the rod 40 is brought'iu contact with the uprightlevers 3G, forcing them back to their normal position, together with therackbars which have been previously released. This movement also raisesthe hammers to their normal position. The adding-wheels being raisedinto engagement with the rackbars will be rotated bythe return movementthereof, and should they be rotated beyond the 9 point the levers 101will be unlocked, thereby permitting the levers 100 to advance theadding-wheels one tooth, when the levers 109 are operated by the returnof the rod 40. During the backward movement of the rod O the carriage isreturned to its normal position, so that the machine is in readiness toprint the total or add another number, as may be desired.

From the foregoing description it will be seen that the act of carryingthe tens is ineluded in a single operation of the machine and is not inany way controlled by any subsequent movement.

It is obvious that the number of type-bars and the number of rows ofstops in the carriage may be varied and similar or other changes made inthe construction of my machine without departing from the spirit of myinvention, and l therefore do not conne the sameto theparticularconstruction shown and described.
